Does anyone have an instructional document on how to change lenses? I have a Tesio300 that came with a 2X lens installed and a 0.5X lens as an extra and I want to use the 0.5X lens but can't. I thought I had it in correctly by removing the ring light and screwing it in underneath but when I tried to calibrate it to the ROI solid block master I could not get the .562 square to fit in the graphics display window. Any help would be appreciated.
